Most of the time when I open Minecraft, when its suppose to sign u in, it doesn't and you have to manually sign in from the web page. Sometimes when u try to sign in manually, it doesn't sign you in and u have to do it again. But if u have to do it again on switch, u have to restart the app to sign in after i signed in again. One of my friends plays on PS4 and sometimes he gets signed out too. I would like if this got fixed.
